Michigan Aerospace Corporation (MAC), a provider of optical products and advanced engineering services, today announced that it has been awarded a U.S. patent for its Autonomous Satellite Docking System (U.S. Patent No. 6,742,745). This mechanism was developed under funding from the Defense Advanced Research Projects Agency (DARPA) and the Air Force Research Laboratory (AFRL) to allow unmanned spacecraft to rendezvous and dock without human intervention. The technology has wide-ranging potential for autonomous vehicle docking in many different environments, including applications with space-based, land-based, airborne, and underwater systems.
